Happy Hot Tubs - the best for your hot tub
PH Plus: 1kg

Use this high quality PH Plus to increase the PH value of the water in your spa (7.2 to 7.6 is the optimum for spas).

If PH is too low, staining or corrosion may occur. PH Plus is also used to increase the Total Alkalinity of your Spa, Hot Tub or pool water. However if accurately needed to be increased, we sell Alkalinity Plus in our Shop.

Simply Test Your Hot Tub or Swimming Pool water and follow the instructions on the back of the tub to increase your PH correctly.
